I could only find 4 names:

1 full prof at Vanderbilt with a real research program who has been listed as PI on a bunch of grants. "Top researcher" may be generous, but based on nothing I'd say reasonable description.

The other 3: 1 is a VU Amsterdam PhD who was on a Netherlands Government funded 24-month postdoc in Harvard who's been at VU Amsterdam since 2017. 1 is an adjunct (on leave) prof from Israel who has worked at a few german universities, most recently an Munster (doesn't qualify for the 30% rule). The last resigned over a year ago and has been contracting at a couple UK universities.

This seems less like "Top researchers leave USA" and more like "Typical Academic Bag Chasing"

Its not just what makes the news. There is a cooling effect happening in recruiting international talent.

Science is heavily international, and if people feel like they won't get funding/wont be safe here, they won't come.

In other news, academics move around.

People love jeering the US because they hate Trump, and this headline is a perfect example. It's gross. Reddit and HN are becoming unreadable because of it. People were literally cheering on Iran (while they slaughtered dissidents), because, hey you're a morally superior person if you oppose the US.
